Latest price update (UTC time):
OWON HDS120 Digital Multimeter Oscilloscope 1MHz Analog Bandwidth High Accuracy 2.8inch LCD 1000V DC Voltage Measurement Current Resistance Tester – Blue.
Banggood ($68.99)
Banggood warehouse is located in China. So I have checked for active coupons (all category coupons and old ones), but there was no working coupon in Banggood. Isn’t it too expensive? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal $67.32)
